MANUFACTURE OF FIGUREID'PILE FABRICS.

Specification of Letters Patent.

Patented Oct. 12, 1915.

Application filed April 17, 1914. Serial No. 832,643.

To all whom it may concern:

Be it known that I, Oscar KoHoRN, a subject of the King of Saxony, and resident of Chemnitz, Germany, have invented certain new and useful Improvements in the Manufacture of Figured Pile Fabrics, of which the following is a specification.

This invention relates to the production of figured pile fabrics in which the pile loops are formed over wires and in which the pile-threads of the warp are fastened in by a semi-rotatory binding. The pile-loops are thereby so strongly bound in the web that they cannot be pulled out. At the same time, the appearance of the goods isthat of a hand-woven Smyrna carpet, because the design is distinctly visible on the wrong side of the goods. The pile-threads of the warp when they do not form'pile are stretched in the goods as filling-threads.

In the accompanying drawing, Figures 1, 2 and 3 illustrate diagrammatically the arrangement of the pile-threads of the warp in different positions; Fig. 4 indicates the draft, thread by thread, of the whole bind-, ing; Fig. 5 is a small design; and Fig. (1'

indicates a section through the goods in.

the direction of the weft.

The mode of manufacture and binding are as follows :There exist three heald shafts or leaves 1, 2, 3. Leaf 2 is intended for-the backing warps. This leaf receives no rise. Leaf 3 raises and lowers the bindingthread. A series of pile threads of the warp are first of all drawn through a heald, provided with a large eye or several eyes, of leaf 1. In the drawing, Figs. 1 to 3, five pile threads of the warp are united in one run; it is, therefore, intended to produce, goods having five colors. The pile threads of the warp are for a second through doup healds which consist of a whole heald and half a heald (Fig. 3)

Copies of this patent may be obtained for five cents each, by addressing the time individually drawn as is best seen from Figs. 1 to 3. The

doup healds are, in conformity with the design lifted bythe Jacquard machine. Every time two wefts for the ground have been woven in, one wire is put in. Previous to the first weft, leaf 8 lifts the binding-thread a. Previous to the second weft, all the pile threads of the warp are lifted by leaf 1 and all the doup-healds on the right of the binding-thread a are lifted from the backing thread. The wire is inserted after the Jacquard machine, in conformity with the pattern shown in Fig. 5, has lifted those pilerthreads of the warp to the left, which are to lie over the wire and thus to form the pile. The pattern is formed as shown by Fig. 6 which is a section in the direction of the weft. By drawing the pile thread of the warp around the backing thread 6, the former receive so firm a position in the web that it is impossible to draw out the pile loops. By these means, the best substitute is provided for a hand-woven Smyrna carpet.

What I claim, is

Themethod of weaving pile fabric having a binding warp, a backing warp, and a pile warp composed of a plurality of pile warps of different colors, which consists in lifting the binder warps to form a shed with the pile warps, passing a weft through said shed, raising the pile threads to form a shed with the binder warps, passing a weft through said shed and douping loops of selected threads of the pile warp under and around the corresponding binding and backing warp threads to form pile loops, substantially as and for the purpose set forth.
